The generator-tank 'C .'s provided with a ffunnel or spongt -E,th`e lower end of which opens iin-to said `:tank through the -oriiiice e,

.closed by an inwardlyopening -rilftp-relire e.

- -fC7, denot e s .gate-Valve Yforlrernt ;.v. `111g `the undissolved carbid, and C? a plng-icock for removing the spent carbid from the-generator. CIv denotes the .removable bell open at ir,the *bottoin .and .closedat thetoprby fthecOVer C1?, which forms an eairtiglh-t joint Vwith the .gen-

` leraterteni: lby :means of .the rubber gasket informed on ,thetanlLQ/the parte be r 1-31, heid 109, sented-on lthe' anniilarlip brshoiride vtogether by the lps?.

This gasket-packing09acts .as aacheckto preventthewater from .rising orerlthe .top .ofthe tank-G in case of runusual 1 pressure, has would be the case when carbid- ',dnstlisnsed. y The bottom face of this cover is centexiu for-1n, assho\\vn, so that thewater eicolnjdensation or moisture will becbnducted to the'vcenteiyand thusretnrnedto the water i n t;he tank without coming in contact with the ca iciocarbidinthe pockets in the carbid f chamber. v

Av'thefgeneratonbell `and formed with an inlet -for '.-filling and a vertical passage-way F3, in which Lare vfixed the deliector-plates VF.

H vdenotes a vertical pipe,its upper open end being .rigidly-fixedin the Atop O32 by the lock-n uts ,Y as sho wn.

H Vdenotes an encompassing pipe or sleeve,

the yupper:end 0E which terminatesbelow the:

@over Vand to which the carbid-chamber is fixed.' Theflower end of the sleeve H is 'provided with a water-inletoriiiceH10, and its iin-A -mediate end carries an internal collar HX, to which verticalpi pe H2 is fixed and its upper end .extendsbeyond the pipe H 13o-receive the in verted'crown ratchet-wheel H5, so th atwrrhen Vthe ratchetwheel 1151's rotated a correspondkiiignievement will wbe imparted-to the carbidchamber, and,as there is a lWater-space between the pipes H, HQ-andiI-I, a perfectwater Seal `is formedbetween the inside and outside of vrthegenerator without the use of stuffingboxes, @andtherebyfpermitting, the carbidc, which normally extends under the lhinged bpttcm to retain it in place, and the upper en dbf said rod terminates in a correspondingly-'form ed trigger c?, which travels around the finnerface of a concentric flangev C5 (fixed tothe fceylerfCi) and which lholds the --toe in {posi-tion -nnder the hin-ged `bottom 05. The

bell and tank by the VWa- .Y forward end of this iian ge C5 fiaresontwardly? IOO so as to extend across the path of the trigger' C2 to engage itand force it inwardly, thereby turning the trip-rod on its axis and turning the toe c under the bottom to hold it in place. This flange is broken away to release the trigger for a space corresponding to the width of the passage-way F3 in the condenser drum or tank F, and immediately above said passageway there is formed in the cover C12 a handhole covered by a removable gasket-packed plate D, from the lower face ot' which a dog D' projects, the outer beveled face of which projects into the path of the trigger c2, so as to divert it to one side and turn the toe c from under the hinged bottom C3 and permit it to F is lilled with cold water, and as the gas' rises from the water in the generator-tank it comes in contact with this cold tank, which cools the gas and causes it to part with its water of condensation, which accumulates on the drum and drips back into the tank C.

O6 denotes an inclined lug fixed on top of the water-chamber F and in the path of the open hinged bottom, so that the latter will ride over said lug and close the bottom, after which the trigger c2 comes in contact with the flange C5, fixed to the cover C12, concentric to the axis of the tank C, which turns the triprod c* on its axis and draws the toe c under the bottom Ci to support it in place.

H3 denotes a rod journaled in the pipe H2, and its lower end carries the horizont-al blades H4, which serve to agitate the carbid in the bottom of the tank C, and the upper end of said rod carries a crank-wheel H2, by means of which the rod and agitator are manipulated.

lt will be noted that the water in the generator-tank rises in the pipe H2 and surrounds the rod H3 to the same level as the water in the tank and in the pipes H and I-l and forming a perfect water seal against the escape of gas without the use of smiling-boxes.

H6 denotes a weighted pawl pivoted on t-he lever H7, swiveled on the vertical stud H12, fixed in the top C12, the free end of the pawl engaging the teeth on the ratchet-wheel H5, and the free end of the lever carries a frictionroller H8, which extends between the parallel arms of the U-shaped rod B5, fixed to a bracket B4, carried by the gas-holder B, which has a vertical movement in the tank A. The teeth are formed on the bottom face of the ratchet-wheel H5, and the toe of the pawl H6 is held in contact with said teeth by reason of its opposite end being weighted. Consequently as the pawl moves forward it carries the ratchet-wheel with it, and as the pawl moves backward its toe slides over and drops into a tooth at the rearward limit of its stroke.

H11 denotes a vertical bar having its lower end fulcru-med in a bracket HEL on the-outside of the generator-tank, and its upper end encompasses the outer end of the lever H7 to support and prevent itcoming into frictioual contact with the top or cover ofthe generator.

|The U-shaped rod B5 is formed with an olset B7, which imparts an oscillating movement to the lever H7 and through the medium of said pawl and ratchet-Wheel causes it to rotate the carbid-cham ber.

B denotes a guide-sleeve extending downward from the top of the holder, and its lower end is connected to the corresponding lower edge ot' the holder by the stay-braces B3.

A5 denotes an axial guide-rod iixed to the bottom J2of the tank Alfor the sleeve B to slide on,and thereby maintain the holder concentric within thetank.

J denotes a diaphragm or false bottom lixed in the tank A, and A6 denotes a vertical pipe extending through the bottom J and terminating at a point corresponding to the predetermined water-level in said tank A.

J' denotes a second diaphragm or false bottom fixed in the tankA below that first mentioned, and in it is fixed an overflow-pipe A7, open at both ends, and A4 denotes the out or supply pipe, the vertical portion of which extends from the lowercompartment A2 through the bottom J,the compartment A,the bottom J, and opens into the rank A above the waterlevel, as shown. This pipe is provided with a lateral branch pipe which extends through the outside of the tank A and connects with the service-pipe leading to the burners.

A3 denotes the relief or escape pipe,leading `troni the lchamber A2, and its upper end hasa telescopic engagement with the hooded pipe B2, fixed in and traveling with the holder B.

\ It will be seen that the lower end of the vertical pipe A4 forms a water seal in the tank, and consequently any unusual pressure of gas in the gas-holder will pass out through the lower end of the said pipe A4 and escape into the tank A2, and thence through the relief-pipe A3 into the atmosphere, thus providinga pressure safety-valve in addition to the telescopic safely relief-pipe A2.

An additional advantage in the lower open ends of the pipes As and A4 is the fact that they provide a discharge-outlet for any condensation that may take'place within, and thus do away with the necessity of outside drip chambers or cocks for this purpose.

G denotes a downwardly -curved elbow which serves to conduct the gas from the generator-pipe Gr below the water-level in the chamber A', and A9 denotes a foraminous hood which encompasses said elbow and acts as a scrubber or washer for the gas by separating or dividing it under the Water in the chamber A.

A8 dehotes an overflow-funnel fixed tothe outside` of the tank A and communicating with the vchamber A2 by means of the orifice a, and itserves as a gage to determine the proper height of the water-level in the tank IOO IIO

A and chambers A and A2, as will be hereinafter more fully explained.

633,844 Y Y e The manner of operating the machine is as follows: The tank A is filled with water nntil it reaches the top of the overflow-pipe A6. The water then passes down through said pipe into the4 chamber A( until it reaches the level of the overflow-pipe A7, through'which it passes downward into the chamber A2 nni til it rises to the level of 'the mouth of the bottom of the funnel.

Afunnel A8, and' all three of'the tanks A, A',

and A2.will now be lled to their proper water-level, with the holder-B sunk to the level of the Water in vthe tank A, so as to exclude the atmospheric air. The generatortank C is now filled with water through the funnel E until the proper level is reached, which is ascertained by the water appearing in the Remove the cover D and fill the water chamber or drum F through one of the pockets in the carbid-chambers. Now iill the carbid-pockets one at a time nn- .til all are iilled. Replace the cover Dand by means of the ratchet-wheel H5 turn the carbid-chamber forward unt-il one of the triprods comes incontact with the arm D to trip the bottom C5 of one of the pockets and discharge its contents into the Water in the tank C, `when the generation of the acetylene gas immediately takes place. The gas now passes through the outlet-pipe G, displacing the wa` ter in the lower end of 'said pipe G, when it connects with the tank A and escaping through the submerged strainer A9 into the space between -thewater1evel and the diaphragm J in the chamber A', and thence upward through the pipe A6 into the gas-holder B, causing it to rise and carry With it the rod B5. The diagonal oset B7, coacting withthe antifrietion-roller on the outer end of the lever H7, throws the pawl H6 into position to engage one of the teeth 011 the ratchet-wheel H5. The gas in the holder passes out through the pipe A4 tothe service-pipes, and as the holder falls, due to the' consumption of the gas,` the rod B5 moves the lever H7 in the `opposite direction, thereby rotating the carbidchamber so asto .present a pocket over the passage-way F3, and, as hereinbefore de-Y scribed, the bottom is tripped and the charge of carbid dropped in the water-in the generartor-tank to producea fresh supply of gas,

vwhich causes the holder to rise with a like resultas before, and this operation is automatically repeated until all of the pockets in` the carbid-chamber are emptied of their eontents. Y Y

In the accom panyin gdrawin gs l have shown my invention in the best form now known to Vby the carbid-chamber and adapted to support the hinged bottoms in a closed position, andV arranged to coact with said dog D' to re-v lease said bottom at a predetermined point, substantially as and for the purpose set forth.

2. In a generator of the class described, the combination with the tank C, of the bell C and irs cover C12, the duplex pipes H and H provided with the orifice H10, lthe rod Hand the blades H4 fixed to the lower end of said rod, substantially as and for the purpose set forth.

3. In a generator of the class described, the

combination with the -tank C the 'bell C' the duplex pipes H and H, the horizontally-rotat ing carbid-chamber and the ratchet-Wheel carried by the said pipes, the pawl and lever coaeting withl said ratchet-wheel, of the tank Aand holder B, and the U-shaped rod B5, coacting with said lever to rotate said 4ratchet- Wheel, substantially as and for the purpose set forth.

In testimony whereof I aix my signature in presence of two witnesses.
